1. Prepare Your Bike
Ensure your Yamaha XT350 is on a stable surface and the engine is cool to the touch. Disconnect the battery to prevent any accidental electrical shorts.
2. Remove the Old Spark Plug
Locate the spark plug on the right side of the engine. Use the spark plug socket and ratchet wrench to carefully unscrew the old spark plug. Be cautious not to damage the surrounding components.

Examine the old spark plug for any signs of wear or damage. This can provide insights into the engine's condition. A worn or fouled spark plug may indicate issues with the fuel mixture or ignition system.
